Be it known that 1, JOHN OCoNXon, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Music-Leaf Turner, of which the following is a full, clear, and exact description.

This invention relates to improvements in music leaf turners, the object. being to provide a device of this character that will be simple in construction and designed. to be attached to a piano or similar instrument, or to a music rack, and adapted. to be operated by foot pressure, thus leaving the hands of the player free at all times to operate the musical instrument, the parts being so arranged that the music leaves may be quickly turned one at a time as the music progresses, or simultaneously turned back to a closed position.

Other objects of the invention will appear in the general description.

I will describe a music leaf turner embodying my invention and then point out the novel features in the appended claims.

Reference isto be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a front elevation of a piano with a leaf turner embodying my invention, thereon; Fig. 2 is a plan partly in section, of the turner mechanism; Figs. 3 and 4 are detail plans showing the turning mechanism in different positions; Fig. 5 is a sectional elevation with parts removed Fig. 6 is a section on the line 6 6 of Fig. 2; 7 is a detail plan showing the turning arms employed; Fig. 8 shows in perspective a covering plate and means for holding a music sheet; Fig. 9 shows one form of sheet holder employed; Fig. 10 shows another form of sheet holder. Fig. 11 indicates the pneumatics employed; Fig. 12 illustrates a portion of a back support for the music sheet. 13 is a sectional detail showing another portion of the back support; Fig. 14 shows a joint connection between members of said support; Fig. 15 illustrates another connection thereof.

Referring to the drawings, 10 designates a base or support which is chambered as indicated at 11, to receive certain working parts of the music leaf turner the center portion of Arranged in the base are inner and outer segmental walls 12, 13 of sultable metal, and OX- tended from the plate 14 to which the walls 1.2 and 13 are attached 18 a wall formed in the forms a track 15, the said track being arranged between the walls 1.2 and 13 and inclined downward from its connection with the plate 14:. The plate 141 has a portion 16 parts 12, 13 and 15 are supported, and eX- tending upward from this portion 16 is a post 17 on which is mounted to turn, a plurality of leaves carrying arms 18, and. on the free ends the music sheets. The first arm of the series has sheet engaging devices consisting of two wires 19; the other arms however, are each provided with a single wire 20 designed to arm for each arm 18; these turning arms 24 are placed one above the other and are held yieldingly together and upon the incline 15, by means of a spring 25 surrounding the arm 24. Each turning arm 24 is provided at its free end with a notch 26 for receiving a finger 27 extended downward. from the free end of the arm 18 co-acting therewith; the

engaging therewith are held by a detent plate 28 mounted to swing on a shaft 29, having bearings in a bracket 30 attached to theiplate 14. Rigidly attached to the end of the shaft 28 from moving too far downward; it is however held. yleldmgly downward or moved to its downward position by means of a coiled spring 32 surrounding the shaft and having other end connected to an arm of the detent the chamber extending through the base. 5 g

are of the circle, the upper edge of which extended underneath the base 10 on which 6 of these arms 18 are devices for engaging with engage with the inner side of a leaf, while the 7 5 The So are turning arms 2-1, there being one turning 8 5 sleeve 22 and engaging with the uppermost 0 several turning arms or leaf carrying arms 5 29 is a detent 31 which will prevent the plate 160 one end connected to the plate 28 and the S1. The end of the shaft 2-9 opposite that to which the detent 31 is connected is curved outward and then forward as indicated at 33;

this portion 33 extends underneath the several arms 24 and engaging with the lowermost one thereof. lhe portion 33 of the shaft is held yielding downward by means of a spring 34 surrounding the shaft 29 and connected with one end to the cranked portion of the shaft and at the other end to the bracket as clearly illustrated in Fig. 4.

idounted to rotate on the post 1.7 is a pinion 35, extended outward from which. is a shifting arm 36 and yieldingly mounted on this shifting arm so is an upwardly extended inger 37; this finger 37 her shown is attached to a shaft 88 mounted to turn in the arm 36, and held yield ingly in one position by means of a coiled spring 39 which surrounds the shaft, one end of the spring being connected to the shaft while the other end is connected to the arm 36. The shaft carrying the finger 37 is designed to rotate in one direction only, during its operation, and to prevent its movement in the opposite direction, when shifting the arms as will be hereinafter described, the inner end of the shaft 38 is turned outward as indicated at 40, to against the inner side of the shifting arm 36. It will be noted in Fig. 3 that the said shifting arm is provided with a slot in which the shaft and spring are arranged. A boss or cam 41 is formed on the free end of the shifting arm 36 and. is designed to rock the shaft 29 as will be hereii'iafter described. Engaging with. the pinion is a rack 42 from which a rod 43 extends to connection with a piston operating in a cylinder 44, and communicating with the interior of the cylinder 44 at the outer end is a pipe 45 which is connected by a flexible tubing 46 with a pipe 47 leading into the lower end of a pneumatic consisting of a cylinder 48 within which is a piston having a stem 49 projected through the top of the cylinder and terminating in a foot-plate 50; oetween this foot-plate 50 and the top of the cylinder 48 is a spring 51. for moving the piston upward, This pneumatic 48 is arranged in a base frame 52 as is also another pneumatic to be described, and this base plate is secured near the foot pedals of the musical instrument, so that the pneumatic may be operated by persons foot; Also mounted on the post 17 is a pinion 53 on which is rigidly secured a returning arm 54 having an upwardly extended finger 55, and this pinion 53 is engaged by a rack 56 havin a rod connection 57 with a piston 58 operating in a cylinder 59, and between the piston 58 and the inner end of the cylinder 59 is a spring 60 for moving the piston in one direction. It may be here stated that the piston in the cylinder 44 is moved in one direction by means of a imilar spring. Communicating with the interior of the cylinder 59 is a tube 61 which has a flexible tube connection 62 with. a pipe 63 leading into the lower end of a pneumatic cylinder 64 having a piston ('55 the stem of which extends upward through an opening in the top of the cylinder and is provided with a foot-plate 66 between whichv and the top of the cylinder is a spring (57 for moving the piston upward.

-When the parts are assembled in the base 10 which has an opening at its top, the walls 12, 13 and the parts contained within the circumference thereof are covered by a segmental plate 68 which at its rear side is provided with a wire 6.) for engaging between the center leaves of the music sheets at the front. Th s wire (39 is designed to be turned downward for convenience in placin the music on the device and it is held yieldingly up 'ard by means of a plate spring 70 attacl'ied to the inner side of the plate 68, and engaging with an outwardly turned finger 71 on a horizontally disposed portion 72 of said wire 65). This horizontally disposed portion 72 being arranged to turn in a suitable bearing attached to the under side of the plate. The music sheets are supported at the rear side by standard consisting of folding sections 73, 74, the section 7 3 being pivotally connected to the plate 14 or to an upward extension 75 thereon and it is held in its upright position by means of a lug 76 on the lower end of the section 73 engaging in a depression or hole in the plate 14, it being understood that the section 73 of the standard has sullicient resilience to permit the said lug to be moved into or out of the depression or hole in the plate. The section 74 of the standard below its pivotal connection with the section 73 is also provided with a lug 77 for engaging in a hole 78 formed in the section 73, thus holding the said section 74 in upright ftllDGD'lODll with the section 73. Mounted to swing on the upper section 74 of the standard is a wire 79 for engaging against the inner side of the music sheets above the wire 69. As here shown. this holding wire 79 has a cam end 80 extended through an opening in the upper end of the standard and engaged by a plate spring 81 which yieldingly holds the wire 7.) against the music sheets.

In the operation, assuming the several sheets of the music to be folded, the parts will be in the position indicated in Figs. 2, 5 and 6, the several arms 24 resting upon the highermost part of the incline 15 and the lower arms 24 being slightly forward of the one next above, and so on, upward. finger 27 of the arms 18 carrying the wires 19 will be engaged in the notch of the lowermost arm 24 while the fingers of the other arms 18 will be successively engaged in the notches of the other shifting or turning arms. The end of the plate 28 is permitted to move sufficiently downward to engage with the lowermost arm 24 at its front side but when. the

The

LOO

pneumatic 48 is operated, the piston in the cylinder 44 will be moved and through the agency of the rack 42 will turn the pinion 35 so that the arm-36 will be operated in a rotary direction. As this arm 36 is moved, the cam 41 thereon, by engaging with the inwardly turned portion 83 of the shaft 29 will rock said shaft carrying the plate 28 upwardly a sufficient distance to free the lowermost arm 24 and by a continued movement of said arm 36 the said lowermost arm 24 will be moved to carry the sheet to the left-hand side of the device. As the first or lowermost arm 24 is moved outward the next one above it will move downward upon the incline 15 and as the arm 36 returns to normal position the finger 37 will turn downward against the resistance of the spring 39, permitting said finger to pass underneath the lowermost arm 24 and then will move upward through the elastic force of the spring to engage against the rear side of said lowermost arm. This operation will be repeated for each leaf of the music to be turned. hen it is desired to return one or more leaves of the music to closed or normal position the pneumatic 64 is to be operated, which through the piston 58 will cause the rack 56 to turn the pinion 53, thus causing the returning arm 54 to rotate and move the several turning arms back to normal position.

It will be noted that the cylinders 44 and 59 are each made in separable sections that is, each cylinder has a fixed head portion 82,

while the remainder of the cylinder is removable therefrom. It is held in engagement with the fixed head portion 82 however, by means of a loop 83 having pivotal connection with the head 82 and engaging with the outer end of the main section of the cylinders; by this arrangement the cylinders may be readily separated for cleaning and for repairing the pistons.
